Genesis of calcic and petrocalcic horizons from Coimbatore, Tamil Nadu: Micromorphology and geochemical studies
Understanding the development of calcic and petrocalcic horizons is important for palaeoclimate reconstruction. The micromorphology and geochemistry of Quaternary calcic and petrocalcic horizons formed in the area around Coimbatore, Tamil Nadu are discussed. The calcic horizons represent the Bk horizons that occur as thick complex profiles ( 300 cm thick) in the foothill regions while the lamin...
متن کاملFibrous-clay mineral formation and soil evolution in Aridisols of northeastern Patagonia, Argentina
Recent studies of soil–landscape relationships in northeastern Patagonia identified fibrous-clay minerals in calcic and petrocalcic horizons developed on old fluvio-glacial plains called “Rodados Patagónicos” (RP). The objectives of this study were: i) to evaluate the occurrence of fibrous-clay minerals in the arid soil environment, and ii) to establish the relationship between the soil propert...

Clay mineralogy of paleosols provides more information about Quaternary climatic changes and paleoenvironmental conditions. Clay minerals of an alluvial fan in eastern Isfahan were studied, using x-ray diffraction analysis. Studied paleosols are located on old Qf1 and Qf2 geomorphic surfaces. Qf1 geomorphic surface is older and topographically higher than Qf2. The results of clay mineralogy sho...
متن کاملتغییرا ت خاک در ردیف ارضی - زمانی دو منطقه اقلیمی در زاگرس مرکزی
Soil development and variability of soil properties on different landforms of Central Zagros were investigated. The study area covers two climatic regions including Shahrekord and Chellgerd with mean annual precipitations of 314 and 1224 mm, respectively. In Shahrekord area, the amount of Feo (amorphous and organic-bound iron) was higher in surface horizons, whereas, the Fed (crystalline, amorp...
